Co-operation and co-ordination

22.—(1) Where two or more responsible persons share, or have duties in respect of, premises (whether on a temporary or a permanent basis) each such person must—

(a)co-operate with the other responsible person concerned so far as is necessary to enable them to comply with the requirements and prohibitions imposed on them by or under this Order;

(b)(taking into account the nature of his activities) take all reasonable steps to co-ordinate the measures he takes to comply with the requirements and prohibitions imposed on him by or under this Order with the measures the other responsible persons are taking to comply with the requirements and prohibitions imposed on them by or under this Order; and

(c)take all reasonable steps to inform the other responsible persons concerned of the risks to relevant persons arising out of or in connection with the conduct by him of his undertaking.

(2) Where two or more responsible persons share premises (whether on a temporary or a permanent basis) where an explosive atmosphere may occur, the responsible person who has overall responsibility for the premises must co-ordinate the implementation of all the measures required by this Part to be taken to protect relevant persons from any risk from the explosive atmosphere.

What the Enforcement Guidance says:

Where more than one responsible person shares, or has duties in respect of a premises
(whether on a temporary or a permanent basis), each must take all reasonable steps to
co-operate and co-ordinate with the others in relation to the measures they take, and
inform the others of the risks to relevant persons arising out of the conduct of their
undertaking.
In premises where an explosive atmosphere may occur the responsible person who has
overall responsibility for the premises must co-ordinate the implementation of all the
measures to protect the relevant persons.
The intention of this article is to require the responsible persons and others with
analogous duties to take all reasonable steps to co-ordinate the measures they take to
comply with the requirements under the Order.
If there is a failure to co-operate or co-ordinate between responsible persons (or those
with analogous duties) the enforcing authority may need to consider enforcement
action to resolve any difficulties.
